Navistar's Engine Plans Include Cummins

September 2012, Work Truck - Feature

Navistar International Corp. will switch its emissions-reduction strategy to diesel exhaust aftertreatment, as competitors have done, and will include liquid urea injection equipment that it will purchase from Cummins. The change follows two and a half years of trying to meet federal limits using only an “in-cylinder solution” that relies on exhaust-gas recirculation.

Switching to selective catalytic reduction (SCR) will begin early next year with its large-bore 12.4L MaxxForce 13 diesel, spreading to other models later in the year. Navistar gave few details in a pair of announcements July 5 and Aug. 2, except that medium-duty engines would continue with no changes well into 2013 because of emissions credits earned with cleaner-than-necessary engine models produced prior to 2010.

Using ICT+

The change comes amid heavy financial losses caused partly by higher warranty costs from troubles with some of its engines, along with a steadily sinking stock price that has angered stockholders. Pressure from major stockholders is thought to have caused Navistar Chairman, President, and CEO Daniel Ustian to abandon his steadfast insistence that the company’s in-cylinder solution would work.

Sales of International heavy trucks fell as customers became wary of the MaxxForce 13, Navistar’s principal large-bore diesel. Its Class 8 market share is now 17-18 percent and its Class 6-7 share is 35-36 percent, the company said.

As part of the Cummins-reliant strategy switch, Navistar will begin offering the Cummins ISX15 in certain heavy-truck models. Navistar last used pre-2010-model Cummins ISX diesels in the first half of the 2010-CY as part of its transition to its own engines without urea injection.

MaxxForce diesels using Cummins urea injection equipment will be called In-Cylinder Technology Plus or ICT+. The new approach will meet the federal Environmental Protection Agency (EPA) 2010 limits on nitrogen oxide, which its advanced-EGR method could not attain. ICT+ and new truck models will restore Navistar’s fortunes, Ustian predicted.

“With the addition of ICT+ and an expanded model lineup, we expect to improve our market share in 2013,” Ustian said. “We expect to return to profitability in the fourth quarter and believe the company will be in a position to improve margins in 2013 as we realize the benefits of our integration and ongoing cost-reduction initiatives.”

Leveraging Advances

Navistar has arranged a five-year $1-billion loan from several banks to shore up its dwindling manufacturing capital and improve its financial flexibility, the announcement said. 

“As previously announced, the introduction of ICT+ leverages the advances Navistar has made in clean engine technology, while also providing greater certainty for its customers, dealers, and other key constituents,” according to the company’s statement, which continued, “To accelerate delivery of ICT+, Navistar has entered into a non-binding memorandum of understanding, under which Cummins Emission Solutions would supply its proven urea-based aftertreatment system to Navistar. This would be combined with Navistar’s advanced in-cylinder engine to create ICT+.”

Production of medium- and heavy-duty trucks will continue as ICT+ is phased in on its engines, with the 12.4L MaxxForce 13 getting it first, in January 2013. 

“During the transition to ICT+, Navistar will continue to build and ship current model EPA-compliant trucks in all vehicle classes using appropriate combinations of earned emissions credits and/or non-conformance penalties,” the statement said. “The company continues to have productive discussions with the EPA and the California Air Resources Board regarding its transition to ICT+.”

Ustian and other top executives spent about two years criticizing competitors’ use of SCR, claiming, among other things, that it put too much burden on customers who had to replenish supplies of diesel exhaust fluid on trucks to feed the urea injection equipment. International truck dealers followed suit. Soon, they’ll build and sell what competitors have been using since early 2010.

    Well I guess you would like some mustard on that crow. You acted like bullies and it came back to bite you square on the ass. Bet you wish now you didn't piss off Ford...
